I have a stromwater drain and pits at the back fence of the house (pic attached).
What plants/shrubs, I can and cannot plant. Also, I am looking for ideas to hide those pits.
Welcome to the Workshop community @bronelchristian. Many thanks for you question, I'd be happy to give you some advice.
When planting in an area near to stormwater pipes it is always best to select trees or shrubs that are small and slow-growing. The water pipe should be in good condition as older pipes made of terracotta are particularly vulnerable to root penetration. It is not recommended to plant closer than 10m from a stormwater pipe, any closer and you should also install Whites 600mm x 5m Recycled Garden Root Barrier. This needs to be installed from the surface and down to at least 60cm deep in between the plant and the pipework.
Some trees that you should not consider- camphor laurel, fig trees, poplars, rubber plants, willows, Australian white cedar, casuarinas, coral trees, elms, large gum trees, liquidambar, jacaranda, illawarra flame trees, pine trees and pepper trees.
If you would like to take some images of the stormwater pits, then I'm sure our helpful members will be able to come up with some great suggestions on how to hide them.
If you need further advice or have other questions, please let me know.
Thanks Mitchell. That's very useful information.
To clarify, it is advisable not to plant trees closer to stormwater pipe. However what about shurbs and veggie plants? Do you think it is still advisable to follow the 10m rule? Also, I have a backyard of 15m, so if I write off 10m that means I will be planting closer to the slab which might be not advisable as well.
I am not planning to plant any trees (if I do it might be dwarf fruit trees), what shurbs and veggies would you recommend to plant over the stromwater pipe?
This is the new development so I hope the pipes used are PVC and not terracotta.
I have attached a picture of the strom water drainage pits, I was thinking to put a retaining wall at the back and create a veggie garden. Do you think this will be feasible or I will be looking at issues in 5years time.
If you take the leaves and branches on a plant and flip them upside down, that is at least the equivalent amount of roots they will have. So your veggies should all be fine and when picking shrubs just make sure you keep to dwarf varieties. You can, of course, come closer than 10m with shrubs, but I would not plant many large trees within that distance.
For the veggies, you might like to consider a raised garden bed as areas with drainage pits often get water-logged. Small shrubs can also be grown in large container pots and that will allow you to move them around as you fill the area.
